Cup lid

ABSTRACT

The present invention provides a cup lid that utilizes fracturing lines to form a novel drinking spout, a cover piece, and a connection part. These fracturing lines include a press-down fracturing line defines a press-down part and a raised fracturing line defines a raised part. The press-down part and the raised part have an overlap area due to the width difference, and the press-down part and the raised part open in opposite. The press-down part and the raised part are transformed as the cover piece and the overlapped area as a connection part. The cover piece can be fixed on the cup plate by using their width difference or clamp structure.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a cup lid and, that has a noveldrinking spout structure.

2. Description of the Prior Art

A lid is used to cover a cup to prevent from overflowing for take-awaybeverages.

In general, a cup lid has a drinking spout for drinking. The drinkingspout has a drinking mouth and a suitable cover piece for covering thedrinking mouth. A user can push/pull the cover piece down/up to open thedrinking mouth. The problem is that the cover piece cannot be fixed, andthe cover piece may rebound back to obstruct drinking.

The inventor proposes a solution to the fixation problem as below.

SUMMARY OF THE INVENTION

For solving the above problem, the present invention provides a cup lidwhich has a novel cover piece designed on the cup plate, configured toform a drinking mouth. The cover piece can be fixed on the plate bypushing, pulling, or pressing the cover piece.

A cup lid, comprising a lid plate and a lid body around the lid plate toadapt to a cup, wherein the lid plate comprises a press-down partdefined by a press-down fracturing line, and a raised part defined by araise-up fracturing line, wherein the press-down part and the raisedpart are overlapping has an overlap area. The overlap area is integrallyconnected with the lid plate to form a connection part, and the opendirection of the press-down part and the raised part are in oppositedirection.

When pressing the press-down part, the raised part is raised at the sametime, so the press-down part and the raised part forms a cover piece andconnected to the cup lid through the connection part, and a drinkingmouth is also formed.

In general, the width of the press-down part reduces gradually from theopen end to the connecting end, and the cover piece can be fixed at thedrinking mouth by pulling the raised part without additional elements.

In another embodiment, a concave shape is designed at the closed end ofthe raise-up fracturing line, so the concave shape is transformed to bea tenon on the lid plate when pressing the press-down part.Correspondingly, a split is disposed in the raised part and the splitcan be used to clamp the tenon. The tenon will be formed by concaveU-shape and the tenon can be clamped into the line split to fix thecover piece.

In another embodiment, a split is disposed on the lid plate in rear ofthe closed end of the raise-up fracturing line, When pressing thepress-down part, the raised part of the cover piece can be clamped intothe split.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, various embodiments of the present invention are describedwith the drawings. However, the present invention can also be widelyimplemented in other embodiments including any substitutions,modifications, and equivalent changes according to the embodiments. Thescope of the patent application is defined by the claims. Many specificdetails of the embodiments are provided in the specification for betterunderstanding, however part or all of the details in some embodimentscould be omitted for brief. The specific steps or elements should not belimitations of the present invention. In the drawings, the same orsimilar elements are represented by the same or similar symbols. Thedrawings are only used for illustration not drawn in actual size, andpart of the details can be omitted to keep the drawings concise.

A lid is used to cover a cup to prevent from overflowing for take-awaybeverages. In general, the cup lid made by paper or plastic material.

FIG. 1 is a top view of a cup lid of an embodiment. A cup lid includes alid plate 20 and a lid body 10 around the lid plate 20. The lid body 10and the lid plate 20 are formed in one-piece. The lid plate 20 containsa press-down part 301 defined by a press-down fracturing line 3011 and araised part 302 defined by a raised fracturing line 3021. The press-downpart 301 and the raised part 302 are designed to have an overlap area40, integrally connected with the lid plate 20. The press-down part 301can be opened downward and the raised part 302 are opened upward.

In this embodiment, the press-down fracturing line 3011 and the raisedfracturing line 3021 are made in a U shape, but it could be arc-shaped,or the like. The open ends of the press-down part and the raised partare in opposite directions.

In this embodiment, the width W1 of the press-down part is wider thanthe width W2 of the raised part, so the overlap area 40 is within thethe press-down part but outside the raised part, near their open ends.In this embodiment, the difference between the width W1 and the width W2is 4-12 mm, and the overlapped length is 4-8 mm, i.e., the width andlength L of the overlap area 40 are 4-12 mm and 4-8 mm respectively.

FIG. 2 illustrates the opened state of the cup lid. If the press-downpart 301 is forced downward, the press-down fracturing line 3011 and theraised fracturing line 3021 are broken, the press-down part is pusheddown and the raised part 302 is raised up. The pressed part 301 and theraised part 302 form a cover piece to form a drinking mouth, and theoverlap area 40 is formed as a connection part to adhere the cover pieceon the lid plate. The user can make the cover piece perpendicular to thelid plate 20 and pull the raised part 302 up to fix the pressed part 301on the lid plate 20 without using additional fixing structure. Inanother embodiment, the width of the press-down part is graduallyreduced from the broken end to the connection end of the press-down part(from W1 to W3), wherein the width difference is 0.3˜1 mm, as shown inFIG. 6, so the press-down part 301 can be easily fixed on the lid plate20.

In one embodiment, a split 50 is set on the lid plate 20 in rear of theclosed end of the raised fracturing line 3021 (i.e. near the center ofthe lid plate). When pressing the press-down part 301 down, the raisedpart 302 is raised up at the same time, the press-down part 301 and theraised part 302 form a cover piece and a drinking mouth. The cover piececan be pushed back along the lid plate 20 and then clamped into thesplit 50 and a drinking sip 70 is formed rounded by the press-downfracturing line 3011, as shown in FIGS. 3 and 4. In some embodiments,both ends of the split 50 can be extended toward the raised part 302 toform an elastic area to enhance the fixation strength.

In one embodiment, the raised fracturing line 3021 is designed to have aconcave shape 3022 near its closed end. When pressing the press-downpart, the concave shape 3022 is transformed to a tenon 303 on the lidplate 20. Correspondingly, a split 60 is disposed within the raised part302. The tenon 303 can be inserted into the split 60. When pressing thepress-down part 301 down, the raised part 302 is raised upward at thesame time. The user can fix the cover piece by clamping the tenon 303into the split 60, as shown as FIG. 5. In one embodiment, both ends ofthe split 60 can be extended toward the tenon 303 to form an elasticarea to enhance the fixation strength.

The present invention provides a cup lid to have a wider press-downfracturing line and a narrower raise-up fracturing line. When pressingthe area rounded by the press-down fracturing line 3011, these twofracturing lines are broken to form a cover piece, a correspondingdrinking spout and a connection part. The width difference between thepress-down fracturing line and the raise-up fracturing line is designedto have the functions of connection and fixation. The user can pull orpush the cover piece to fix the cover piece on the lid plate.
